Vent Installation
Slide the vent sections together and turn 1/4 turn until the sections lock in place.
Screws are not required to secure the vent. However, three screws may be used to secure vent
sections together if desired.
High temperature sealant is recommended at the appliance starter section connection (use high-
temperature silicone or Mill-Pac®).
If disassembly is required, at time of re-assembly check to see if the vent creates a tight fit. If it does
not, apply high temperature sealant to the joints of the affected sections.
Horizontal sections require a 1/4" (6mm) rise every 12" (305mm) of travel.
Horizontal sections require non-combustible support every three feet (e.g.: plumbing strap).
Approved Vent Configurations
Exhaust Restrictor Position
An exhaust restrictor is built into the appliance to adjust the flow rate of exhaust gases. Depending
upon the vent configuration, you may be required to adjust the restrictor position. The charts for vent
configurations detail the correct restrictor position.
Slide the restrictor to the correct
restrictor position (see the illustration
below). Screw location indicates
restrictor position. In this example, the
restrictor is set in position # 5. Tighten
the screws to secure the restrictor.
